I can't really help with the specific request, so feel free to disregard my own question/curiosity!
Is there something you feel lacking in aikido, some area in which you don't find yourself fully engaged or adequately challenged? Because it seems to me what you are describing is not getting tugged TO a specific other art so much as finding yourself wanting something other than what you have. Maybe if you can clarify your goals it will make next step or choice of a second art easier to identify.
